Music Deleted From The iTunes Store

I went to the iTunes Store, searched Hannah Huston The Voice, and all of her songs were taken down. I then searched simply The Voice Performance, and nearly all the contestants songs have been deleted from the actual store. WHAT'S GOING ON!!?? All the music for Hannah Huston, Bria Kelly, Ryan Sill, even Danielle Bradbery's performances have been deleted. Is there a glitch for The Voice music or something? Cause when I searched Bria Kelly iTunes on google, all her music was there. Please, if anyone knows what happened, please tell me! 😢😠
